Am I Alone In This Ability?

I come from a family that comes from Puerto Rico. From where I can remember they all did santeria. My grandmother used to tell me it was in my blood. I see things that others can't I feel cold chills when I walk in to a room and I hear a voice that wakes me up every morning at 3am and I see bugs like spiders. I have tried to ignore it but I can't anymore I don't know what to do. It first started when I was 8 years old it was small things like shadows dogs they weren't there. And then seeing shadows move from room to room. Now I get the feeling that I'm never alone like somebody's watching me,I'm sure that I know they're there and other people that the practice the same religion have told me that there's things watching me that I should feel lucky but I don't I just want to stop, but I'm not the only one my two younger brothers see the same thing but it's not as strong as me I see them more often I feel them just wanted to be over I just want a normal life... Money when I was younger I actually like the feeling of being different seeing things that others couldn't and feeling things that other couldn't but now it's just the overwhelming. I feel like now that they know that I know they're there you will never leave me alone. Will be days when I don't feel anything or see anything mostly when I lock myself in my room. But I don't like the darkness I have to sleep with a light on, I wake up like something wants me up I get cold chills all the time if there's anybody out there that's going to the same thing or have someone to help please let me know...
